The cost y (in dollars) to rent a lane at the bowling alley is proportional to the number x of hours that you rent the lane. It costs $18 to rent the lane for 2 hours.
a) Write an equation that represents the situation
b) Interpret the slope
c)How much does it cost to rent the lane for 3 hours?

Answers

Answer 1

Answer:

a) y = 9x

b) For every increase of 1 hour the price to rent the lane increases by $9.

c) $27

Step-by-step explanation:

a) Since it costs $18 for 2 hours we can infer that for every 1 hour it costs $9.

So, the equation would look like this:

y = 9x

b) In this context, for every increase of 1 hour the price to rent the lane increases by $9. Like the question gave us, the price for 2 hours cost $18.

c) Plug 3 into the equation:

y = 9(3)

y = 27

Therefore, it costs $27 to rent the lane for 3 hours.

I hope this helps!!

Answer 2
A) Y=9x
B) m=y/x
M= 18/2
M=9/1

For every a hour you pay 9$ (which btw is bull)

C) 27$

Initial cost x hours or

3(x)=y
3(9)=y
27=y (that’s the same thing as y=27)

The total cost of the 3 shirts including shipping is $71.83. They want to know how much each shirt costs without shipping so you are going to do $71.83 subtract $7.99. This gives you $63.84 for the 3 shirts without shipping. Now you are going to take $63.84 and divide by 3. This comes out to be $21.28 For each shirt.
I was just solving that equation out for you just in case. What you need to put in the box is this:

3s + 7.99 = 71.83

3.8% is written in the decimal form.

= 0.038

r = 0.038

t = 15 years

Put in the formula

Amount = $831.25

Therefore the balance after 15 year is  $831.25 .

The difference of the polynomials (5x3 + 4x2) – (6x2 – 2x – 9) is 5x3 – 2x2 + 2x + 9.

Step-by-step explanation:

Answer:

5x3−2x2+2x+9

Step-by-step explanation:

Distribute the Negative Sign:

=5x3+4x2+−1(6x2−2x−9)

=5x3+4x2+−1(6x2)+−1(−2x)+(−1)(−9)

=5x3+4x2+−6x2+2x+9

Record the high and low temperatures that are forecast for the next 7 days in the table below. In the columns titled, Difference," record the change in temperature from the day before. To do this, subtract the previous temperature from the current temperature Be sure to use positive and negative numbers as needed! For example, if yesterday’s temperature was 70 and today’s temperature was 65, the difference is 65 – 70 = -5.

Write a mathematical expression using the information from your table to answer the following questions:
What is the mean change in the forecasted high temperatures? Remember, this can be found by averaging the values in the Difference column for the high temperatures. Show your work and steps. If your answer is not an integer, explain what two integers your answer is between.

What is the mean change in the forecasted low temperatures? Remember, this can be found by averaging the values in the Difference column for the low temperatures. If your answer is not an integer, explain what two integers your answer is between.

Answers

Answer:

What explains the difference in temperatures between the two cities?

Step-by-step explanation:

Answer: Using the mean concept, it is found that:

1. The mean change in the forecasted high temperatures is of -0.33ºC.

2. The mean change in the forecasted low temperatures is of 0.5ºC.

-----------------------------

The mean of data-set is given by the sum of all observations divided by the number of observations.

Item 1:

The changes in the high temperature are: 2, 1, -1, -1, -1, -2

Thus:

The mean change in the forecasted high temperatures is of -0.33ºC.

Item 2:

The changes in the low temperature are: 2, -2, 2, 1, 0, 0.

The mean change in the forecasted low temperatures is of 0.5ºC.

7/8m − 1/2= 3/16m + 5

Answers

Answer:

One Solution    m = 8

Step-by-step explanation:

7/8 m - 1/2 = 3/16 m + 5            Add 1/2 to both sides

7/8 m = 3/16 m + 5 + 1/2

7/8 m = 3/16 m + 5 1/2             Subtract 3/16 m from both sides

7/8 m - 3/16m = 5 1/5              Change 7/8 to 14 / 16

14/16 m - 3/16 m = 5 1/2           Subtract on the left. Change 5 1/2 to 5.5

11/16m = 5.5                                 Multiply both sides by 16

11m = 5.5 * 16

11m = 88

11m/11 = 88/11

m = 8

What is the value of the expression m8−(34−n) in simplest form, when m = 6 and n = 18?

please hurry

Answers

Answer:
N is just simply 18

so 6*8-(34-18) and use pemdas to solve

34-18=16

6*8-16

48-16

32

so the value is 32

The value of the expression for m = 6 and n = 18 is 16,79,600.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is the expression as -

m⁸ - (34 - n)

The expression given is -

m⁸ - (34 - n)

Now, for m = 6 and n = 18, we can write -

6⁸ - 34 + 18

6⁸ - 16

(6 x 6) x (6 x 6) x (6 x 6) x (6 x 6) - (16)

36 x 36 x 36 x 36 - 16

16,79,616 - 16

16,79,600

Therefore, the value of the expression for m = 6 and n = 18 is 16,79,600.
